The article is devoted to the actual problem of producing unburnt wall products of compression molding with improved and high efficiency in terms of thermal and engineering properties. The article notes the relevance, attractiveness, and wide use of unburnt pressed products in modern civil engineering. The raw material composition and production technology of unburnt wall products of compression molding are described. The traditionally used aggregates for unburnt wall products of compression molding are reviewed and their properties are analyzed. High average density and high thermal conductivity are noted in these products. The objective is to improve the thermal characteristics of these products while ensuring their strength properties. For this purpose, it is proposed to introduce a porous component of siliceous rock called opoka (silica clay) into the raw material composition of products as a mineral filler. Opoka collected from three different deposits was reviewed, its characteristics given, and the raw material analyzed. It is noted that the porosity and average density of opoka depend on its deposit. The effect of porosity and average density of opoka on the average density, compressive strength, and water absorption of unburnt wall products of compression molding based on opoka with different porosities from different deposits is described. The effect of the properties of opoka on the properties of unburnt wall products of compression molding is explained. It is confirmed that the use of opoka in the production of unburnt wall products reduces the average density of the products and improves their thermal and engineering properties. The appropriateness of manufacturing large-sized hollow wall blocks based on opoka is substantiated. |
